To have confronted DH's cousin for flirting with him?

My husband and I have been together for 18 years, married for 12. We have two children, aged 15 and 13.

Years ago, long before our relationship, when DH and his female 1st cousin were teenagers, they had a brief, secret relationship with each other.

At first, I thought they just slept together, but over the years DH confided in me that he had slept with her once while staying at her house for a week during the summer holidays when they were both 16, but that they also wanted to be together but knew they could never tell anyone.

They lived in different parts of the country and rarely ever saw each other.

My DH has told me he's actually quite angry with his parents for putting them in this position. They were teenagers, who didn't grow up together, rarely saw each other, and yet when the family would meet up once or twice a year, they would always stay over and the kids would be put in the same room, on bunk beds and camp beds, without any thought of the fact that they were developing and going through puberty, just assuming they were innocent kids. He says the curiousity and strong feelings were inevitable and his parents and other adults should have been more responsible.

Anyway, noone at all knows what happened except DH, the cousin, and me.

When they reached young adulthood, the cousin emigrated to a different country and DH and I have only seen her twice in the last 15 years.
However, we are all currently all Holiday together! MIL recently won a large amount of money and took the whole extended family, 17 of us in total, away on a huge Holiday. Cousin is here.

We have been drinking every night and cousin, who is now in her late 30s, and doesn't have a husband or kids of her own, keeps relentlessly saying flirting with DH. Telling him he looks great in shorts, whistling when he takes his top off on the beach, making silly sexual jokes, and hugging him by coming up behind him and resting her head on his shoulder. Noone else seems to notice and DH says not to worry about it as he doesn't feel anything for her and nothing is going to happen and she's just being playful.
But I've noticed she's not like it with any other males here. Just DH.

The final straw for me came last night when she sat on DH's lap while we were all sitting around drinking and put her arms around his neck, and kissed his cheek.

DH just laughed and told her to get up then got up himself and went to the bar.

Again, we had all had quite a lot to drink.

A few minutes later, I went off to the toilet and she was coming back towards me. She was quite drunk and came over with her arms out in front of her to give me a hug. I stepped away and looked her right in the face. I said "Stop flirting with my husband. Don't think I don't know your history. If you come anywhere near him again, I will tell everyone about you two." She looked utterly shocked. I walked away. She must have gone straight to bed.
Today, she's been really quiet all day. Everyone's commented on it but they've just assumed she's really hungover.

MIL and I were sitting on the beach and she commented that this trip has been good for her. She's had a hard time lately as a bloke she was going to marry cheated on her with his ex wife and then went back to her. She's really benefitting from being with family to support her as she's so alone out there.

I feel really guilty for saying that to her last night. I just got so jealous seeing her sitting in his lap, looking amazing in her tiny sundress, knowing their history and she was probably his first love, and felt so insecure. The stupid fling they had was so long ago and they were young and I know at least DH deeply regrets it and is embarrassed about it.

I'm worried I've now ruined her holiday. I didn't know she was going through that. I've been chatting to her to be friendly and get to know her but she never mentioned it

Was I unreasonable?

I suspect she thought this 'we will never tell anyone' pact would hold for life, that they were both locked into a 'we are each others secret true loves' so she was distraught to realise that actually you, his wife, were made aware and she is largely insignificant.

The tantrum and flounce is just more of her manipulative main character bullshit. She's awful and a sad person.

I accidentally quoted the wrong reply, this is what I think could be a good guess at her motivations

CalmTheFuckDownMargaret · 08/05/2026 14:10

She’s been using the fact that they are cousins and that nobody would suspect the worst to conduct herself totally inappropriately with a married man. Remove the cousin bit and you still have a woman whistling at a married man and throwing herself all over him rather territorially. He’s your husband. Where’s her respect and boundaries? She should feel embarrassed. I’d bet that her recent relationship’s unhappy end has led to her being a bit desperate for validation.

Goditsmemargaret · 08/05/2026 13:38

Right so two consenting teens have sex and he's to blame? Why isn't he a fucked up mess then?

I didn't say he was to blame, but different people are impacted by things differently. What one person sees as "just one of those things" could be extremely traumatic for another, especially as they get older and gain more understanding.

Not your fault. People can be damaged and have mental health issues while also being complete arseholes who know better. Her personal issues are no justification for her behaviour. The world doesn't owe her anything, and you and DH certainly don't owe her a week of... what exactly? Sexual flirtation with your DH? Should your DH give her a sympathy shag too?

It's best she's gone. And I'd give that entire side of the family a wide berth for a while.

Edited

This could be spot on. She’s obviously going through some stuff and having this dirty little secret might have been quite thrilling for her, knowing she could flirt and thinking she and your DH were the only ones in on it, and to realise you know and could see her crossing boundaries all along must have been quite humiliating. This might be the thing that makes her realise she’s hit rock bottom OP. Either way you’ve done nothing wrong and saved her from embarrassing herself further

I probably worded it badly in my OP and I probably shouldn't have even said it. I suppose I was trying to defend him somehow, knowing what people were going to think and say.

He absolutely blames himself, it's just that when we were talking about it in the context of talking about our own teens, he says it was stupid to leave opposite sex teenagers who barely knew one another to sleep in the same room and that they shouldn't have.

That doesn't mean he doesn't recognise it was their own poor decision.

I do agree with him. I must have a twisted mind but I wouldn’t even put my 13yo and 12yo neice and nephew share a room because familial childhood abuse happens sometimes. And I’d never want to be the one who made them share a room when they were with me. Obvsiouly this isn’t want happened as they were both consenting but again 16yo are hormonal and not fully mature yet. So I do get where he’s coming from.

I remember my half brother and his step sister had a thing when they were teenagers and people were horrified, as they’d known each other from 4/5. But they didn’t grow up in the same house but people expected them to view each other as siblings. Again, not the same as they weren’t actually related, but yeah I think people are naive to think that these things would never happen and should probably be more cautious with their teens

outerspacepotato · 08/05/2026 13:52

She's got issues well above your pay grade to deal with. The best thing for her would be rehab and lots of therapy.

You were correct in setting boundaries around your marriage with her. She sounds like she's got some narcissistic traits exacerbated by substance abuse and like she's been enabled by her family who are afraid to rock the boat. You aren't the problem here at all so don't feel guilty about putting up a boundary with someone getting sexual with your husband in front of your family.

Your husband may talk a good game, but there's some future faking going on there. He didn't set those necessary boundaries and he plays the victim.

It's a shame this whole cluster fuck detonated on a family holiday.
It's not your fault!
Enjoy the rest of your break as much as you can and let her support people support her.
Hopefully she turns a corner and gets healthier.

I’d be wondering whether she’s a mess because she had an inappropriate relationship with her cousin when she was young and vulnerable personally 🤷‍♀️

SerafinasGoose · 08/05/2026 13:36

Well, she's outstanding in the exhibitionism department, isn't she? She comes across from your descriptions, @Temporaryusernamename, as a highly manipulative, exhaustingly melodramatic pain in the arse. That she's evidently unused to being admonished is clear from Aunt's response in dancing attendance on her whilst she rocks the boat for everyone else. Your confrontation of her the other night, OP, might have been one of the few times anyone has challenged her extraordinary behaviour.

Whatever her reasons, the whole family is now being 'punished'. She has what she wanted: everyone tying themselves in knots to unpick what the matter is, you and DH feeling guilty, and her own mother worrying herself sick whilst she makes a deliberate mystery of the cause of her angst. This is extremely manipulative, childish behaviour.

She is clearly struggling. She's also just as clearly a grown, functioning adult who manages the control of her own business just fine. The rebuke should have come from DH but she was making an utter fool of herself and, at the very least, 'hinting' as to their past. That's deplorable. I do also think it now likely that she will tell her mother. You can't control that, but equally, no matter how vulnerable she is, you don't bear responsibility for her actions. Nobody forced her to fuck her cousin. Nobody forced her to drape herself all over him right in front of his wife. Nobody told her to flouce when pulled up on her bizarre, inappropriate conduct. Those were her own decisions. You have nothing to feel guilty about.

FWIW, it sounds as though this particular branch of your family would be no great loss to your lives. Who has the time or headspace for histrionics like this?

Well this woman is a total mess. She connects with men on a sexual level and both sexes on a victim level. I'm sorry to say but she seems very damaged and I also would wonder was this what led to them sleeping together - at least from her side.

Your husband seems to have his priorities right.

This woman is not your responsibility. You were pushed to your limits, you snapped briefly and then you tried your best.

She's an adult, it's her job to get therapy and addiction treatment, nobody else's. She made the whole fucking thing about her. I'd be thanking your lucky stars you don't have to see much of her.

Well it was never going to not be awkward. At least your DH supports you.
This is de-railing but you say your DH blames the parents for putting all the cousins together in one room for their childhood into adolescence to 16yr olds years?? That obviously demonstrates a lack of boundaries on their part but what was /had been going on all the years up to him & his cousin having full blown sex? You don’t get to that without some build up. I just feel like he’s blamed the parents & that kind of shuts it all down. If she’s a chaotic individual now & had poor boundaries then - it does make you wonder how long their contact with each other was sexualised for & like so many others have said - they spent times as kids/young people with their cousins but didn’t get sexual with them. It does make me wonder if she’s been sexualised from an earlier age. And by who? You’ll never know. But I’d find it very unsettling personally. I don’t know if tables were turned & they were your DC we’d be that content with them being in love with eachother. Sorry probs what everyone else was saying earlier in the thread.

I probably worded it badly in my OP and I probably shouldn't have even said it. I suppose I was trying to defend him somehow, knowing what people were going to think and say.

Its really interesting that everybody is fussing about the potential genetic risk associated with cousins having sex.

But actually, you are all ignoring the injury that has actually happened. The OP's DH and cousin are former lovers, who can't get away from going on holiday together. And one of them has, as a million threads about men going away with former flames have predicted, behaved pretty badly.

What is gruesome in this situation is that the OP can't call it out, because then she's the pervert for 'sexualising' the relationship two close relations have. If it was any other woman she would be supported for admonishing a woman for sitting on her husband's lap. But in this situation? She's the weirdo.

The husband and cousin allowing their relationship to be consumated have created a very difficult situation for the rest of the family and future partners/OP. But because it is so taboo they won't be pulled up on it.

'Because if we say that I confronted her for flirting with DH and they don't know the history I am going to look like the fucking weirdo.'

Yep, this is the exact point I made earlier. The real problem has little to do with six-toed babies.

Hope you are ok, OP.

Gonnagetgoingreturnsagain · 08/05/2026 12:31

I feel a bit bad for her tbh. Yeah she did a stupid thing but sounds like she’s messed up. She needs support.

ReadingSoManyThreads · 08/05/2026 12:30

Wow, she really is a mess. Oh dear. Listen, you weren't to know, so don't blame yourself.

glowfrog · 08/05/2026 12:28

Don’t feel guilty. She is clearly in a very bad place and she may need to hit some kind of rock bottom before she can start to address it. Her behaviour towards your DH was not ok and you were right to confront it.

I hope she is able to face her problems and make a change.

Temporaryusernamename · 08/05/2026 12:21

People! I am so sorry I haven't updated. I've had a crazily busy few days on Holiday but we are now waiting in the airport on the way home.

So DH came back from his hike just before dinner the other night, we were able to speak briefly before as we were getting ready. I told him I'm feeling really uncomfortable with cousin's flirting and that I had a word with her the other night. He wasn't surprised, and he immediately said that he really should have stopped it before it got to the stage where she sat on his lap, and that actually, he was going to pull her aside that night as he could see he'd let it get too far and he saw the look on my face when she did it, but then she went straight to bed after so he didn't get a chance to do that, and then was away all day. I told him that yeah, she went to bed straight after because I spoke to her...
And he said that he was really sorry and that he just saw her as being a bit drunk and stupid and harmless and he was worried saying anything might disrupt the holiday and make things awkward but that he should have just done something. He said I 100% have nothing to worry about, and that he isn't remotely interested in her and actually just feels really sorry for her and thinks she's a bit "pathetic" as her life is a bit of a mess in loads of ways.
Turns out MIL (who likes a bit of gossip) told him too about the ex thing and the getting cheated on, but actually went a bit further, she said that she has had a drinking problem for years, and also a bit of a coke problem which no-one knows if she still has because she denies it, and that actually the bloke she was going to marry had also got her pregnant, and had asked her to marry him after finding out about the pregnancy but then left her and went back to his ex so she had an abortion two months ago so she's also going through that.
He said this is no excuse for her behaviour but that's she generally just a bit of a mess and he just humoured her because he feels sorry for her and doesn't really take her seriously, feels bad about telling her off when she's so vulnerable, and worries about causing a scene. He said that was wrong though and he should have told her sooner before the sitting on his lap thing.
He asked exactly what I said to her and I told him. I could tell he was slightly pissed off that I threatened her with their secret but he knew better than to say that. I did then say that I would never have actually told anyone, which I wouldn't have really.
So anyway, that all said, we went down to dinner. Cousin was there, but sat at the other end of the table. She was already pretty drunk when we got there and was drinking more and more, then about half an hour after dinner, my husband and I were at the bar by ourselves talking and she comes stumbling up to us and says "well you both hate me now, don't you?" and I said "no, of course we don't, we just needed to set some boundaries, but could have gone about it better way, it's done now so don't worry, we can just move on"
And then she said "well, I'm going to go home tomorrow, I've booked an early flight so you don't need to worry about me any more " and I said "there's really no need, like I said, we can just move on from it" and she was like "well it's done now" and then DH's auntie, her mum, comes over and says "what's done now?" and cousin said "I'm going home tomorrow, I've booked a flight, I'm GOING, don't want to talk about it" and she walked off, and auntie walks after her. Me and DH are sat there thinking shit hit shit, it's all going to come out.
15 minutes later, auntie comes back over to us, and says "whats wrong with her, she's in a right state and keeps insisting she's leaving tomorrow and she's booked a flight for 11 but won't tell me why" and we kind of played dumb, said she's upset and we're not sure why which I feel bad about but I wasn't sure what the hell else to say.
Because if we say that I confronted her for flirting with DH and they don't know the history I am going to look like the fucking weirdo.
So Auntie says can you guys go and see if you can get it out of her because she's always thought the world of you (meaning DH). So we say yes, because we can't really refuse, and then we go up to her room. On the way up, I tell DH that he is dealing with her, not me, but I'm coming in case she fucking tries anything else and DH is just like FFS this is such a mess. We get to the room and she's just lying there on the bed with the door open, so we go in and she says "Please just leave me alone, I'm going tomorrow and there's nothing you or mum can do about it, I'm sorry for all the trouble I've caused but I will be gone in the morning so please just shut the door and leave me alone."
So now I start to feel bad and I ask her if she's going to be OK and she says "Yes, I'll be fine, but I shouldn't have come on this Holiday, it was a huge mistake" and DH says "look, you've had a lot to drink, why don't you just get some rest, your flight isn't until 11, so just see how you feel in the morning, there's no need to go, we can just move on" and she says yeah, sure, I'll see how I feel in the morning but I am asking you now to please leave me alone. So we leave and tell Auntie we can't get it out of her either and Auntie says "Oh she'll be fine in the morning".
But nope, she left early the next morning before any of us got up and at 11am sent a picture of herself on the plane to the Holiday whatsapp group saying thank you to MIL and to all the family for such a wonderful time but she's had to go home early due to a crisis at work (she owns a small business) and everyone was like "Aw what a shame" and Auntie was like "Oh, well, that's not what it sounded like last night" and is obviously still suspicious but said she will talk to her when she gets home (Auntie lives in the same place cousin emigrated to).
So now me and husband feel pretty shit, guilty, and quite worried about cousin. Auntie is probably going to grill cousin once she's home, and we're all kind of in a bit of a crappy limbo land, not really sure WTF is going to happen.
Make of all that what you will!! :(

I don’t think you read this correctly at all - I wasn’t suggesting he would be sleeping with his own child, I was suggesting OP’s child would be sleeping with his half sister and then blaming op for putting them in this position.

Half siblings would be deemed incest in law, and therefore not legal. Cousins is legal. Gross, but legal. And all too common in some parts of the country, rural and city alike.

AussieManque · 07/05/2026 09:17

Surely he would be sleeping with his child in this example, not his half sister? And he would know it was his child and there would be a big age gap. The comparison doesn't stand.

First loves truly have a deep connection.
I know you were acting a bit like a petulant child when you said " I won't be updating, so there"

So here is the honest truth for you OP and anyone else who may be going through similar.

I know cousins that were forbidden to have a relationship to the point that their own family would disown them,
However, their love was so strong and couldn't be denied. They met again and had children together and those children called themselves pedigrees at their parents funeral. They called it a special bond that couldn't ever be broken.

You know your husband found her attractive and thats the reason you went in on her rather than him.

I hope that this hasnt destroyed your relationship with your husband. And sorry but if he didnt actually tell her to leave him alone then he probably l Iiked it.

Talk it through with your hubby to put your mind at rest, though a bit of me wonders if there isn't always a bit of something lingers on after a sexual encounter, however long ago.
You've warned her off, I would either do the same with hubby - who seemed to be enoying it a bit too much - or keep a very close eye on them for the rest of the holiday. Whichever you do, neither her nor his behaviour was within appropriate limits so you are well within your rights to address it.

I guess maybe for you, as you wonder this. For me I can categorically say no, anc certainly not for young boyfriends. Some ex’s I’d not look at again quite frankly. I would think more she feels shame.
